imagine 4 persons
4 heads 8 legs
a 2 ch amp has 4 speaker outs R + - L + -
2 on left ch
2 on right ch
Bi Wiring with speaker wire is like 2 home runs +-+-L +-+-R
2 positives tied to each other at the spade termination as 1 positive +
2 negatives tied to each other at the spade termination as 1 negative -
As the speaker wire goes out to the bi wired speaker
think of 2 pairs of pants it splits into 4 at the speaker
2 pos +
2 neg -
Best,
